If you set the 'EFS Decrypt Files' option to No, the Initial Encryption Wizard will ignore EFS encrypted files. They will not be re-encrypted by SafeGuard LAN Crypt, even if an encryption rule has been specified for them.

After configuring this option, users cannot change it in the Initial Encryption Wizard. Users can only configure this option themselves in the Initial Encryption Wizard if it has been set to not configured here.
